[QUOTE="John Roberts, post: 32689, member: 126"] Re: 70v System vs traditional... You don't mention where you are geographically. 100V is typical for overseas constant voltage systems, 70V in the US. I am not aware of many receivers with CV outputs, and 8 ohm speakers don't work on 100V CV lines without a step down transformer. Were you using a step up transformer or driving the 8 ohm speakers directly from the receiver, or perhaps with a volume pad? You can make adequate volume with 70-100v or low impedance systems.. there will be more wire losses with low impedance distribution, but perhaps more LF playback response. Not clear what you currently have/had... JR [/QUOTE]
